Design Evolution


Design is something that humans do on purpose, and natural selection doesn't "do" anything on purpose. We design genetic networks and metabolic pathways and we try to understand the logic of how cells have evolved to develop better "design principles". 
We use evolution to help us optimize enzymes and pathways,
designing schemes and selections for directed evolution, and we worry about what will happen to the products and technologies built with synthetic biology if they continue to evolve. Variation, mutation, and evolution of a product that is made by or actually is a living organism has to be carefully managed and controlled in biotechnology and industrial food production, and will play a large role in future synthetic biologists.
They talked with one of the designers who outlined their process of "mutation," where they prototyped many variants, changing the shape and thickness of the handle and the position and angle of the bristles, and the process of "selection," testing the variants with consumers and having them choose the one they liked best. An interesting essay from Next Nature looks at a similar "evolutionary" process in the design of the razor and "natural selection" by buyer behavior and markets.
The most common objection for design evolution is that "people play a role in the process, so it can't be evolution". This reasoning is tempting, however, it also positions people outside of nature as if we are somehow placed outside of the game of evolution and its rules don't apply for us.
Another objection might be that my razors cannot be the result of an evolutionary development because they are made of metal and plastic and not a carbon–based biological species. to me design is always honest and advertising is all about lying :)
